The nucleus is the solid part of a comet.

Halley's comet, the actual solid nucleus part, is around 8km wide by 15km long. It's gas and dust tails can be spread out over millions of km though. The diameter of the Earth is around 12,700 km, so by contrast, the diameter of the nucleus of Halley's comet is around 0.1% the diameter of Earth.
The nucleus of a comet is the solid, icy core of the comet. It is composed of a mixture of ice, rock, dust, and organic compounds. As a comet gets closer to the Sun, the heat causes the nucleus to release gas and dust, forming the characteristic coma and tail of the comet.
We believe comets have a composition like a dirty snowball. They contain alot of ice and dust. The ice does trun into a gas when the comet approaches near to the sun and this causes the comet's tail to form.
The part of a comet around the nucleus is called the coma. It is a dense cloud of gas and dust that forms around the nucleus as the comet approaches the Sun and starts to heat up, creating a glowing halo.
The nucleus and the coma compose the core of the comet. The nucleus is the solid, rocky part at the center, while the coma is the surrounding cloud of gas and dust that forms as the comet gets closer to the Sun and begins to vaporize.
The electronic clouds (orbits) around the nucleus is extra nuclear part of atom.
The bright glowing gases at the central part of a comet are called the coma. They are produced as the comet comes closer to the sun and the heat causes the ice and other volatile compounds on the comet's surface to sublimate, creating a cloud of gas and dust around the nucleus.
The densest part of a comet is typically its nucleus, which is a solid, icy body made up of dust, rock, and frozen gases such as water, ammonia, methane, and carbon dioxide. The nucleus is surrounded by a coma, a cloud of gas and dust that forms as the comet gets closer to the sun and begins to heat up.
Yes. Halley's Comet is a comet that orbits our sun, and the definition of "Part of the solar system" is 'Any object that orbits our sun.'
